I also use IS very heavily between 70-99mm and value the difference between acceptable and tack sharp.

IS is a good thing for longer lens. Even my binoculars have IS

However at the shorter end motion blur becomes the main enemy. So for example at 24mm on a ff the 1/30 shots will be sharp, yet any movement of the subject will be blurred.

From experience I would say that motion blur becomes an issue (except while panning) when shooting under 1/60. On a crop this would be about 40mm where IS isn't needed.

That's certainly reasonable. beyond that, the value of IS at even shorter focal lengths is more evident on a 1.6x crop because lower ISO speeds are often used to avoid noise especially when there is no subject movement. Here the rule of thumb from the film days is still good guidance, i.e. to know when IS is contributing or should be used.

That said we should note that some have never had the need or desire to shoot handheld 28mm f/2.8 at 1/6th second.

After hours of searching and reading 7D2 spec speculations, I have come to a point where I think 7D2 will not have a FF sensor. It can have, either APS-C or APS-H,still, the probability of having an APS-H is very less.

This is simply based on a theory:

Lets assume a person, very new to the DSLR community, wants to buy a DSLR. He would go with the Rebel series if he is not a great spender(most likely with T2i, with its lesser price and a great review ). If he is ready to spend more, then he would go with 7D for its amazing power. A person having a Rebel series would like to upgrade to 7D and not to 60D as 60D is not that much of an upgrade. So where does 60D stand? Does it have a strong base like Rebel series or 7D? No.

7D has its legendary sales number and a huge fan base. So Canon would not destroy 7D's line up just to reply for Nikon's cheap entry level FF DSLR. And there are rebel DSLRs to cope the need of entry levels or photo enthusiasts. So we do not need 60D line, as there are many APS-C cameras for each and every need. Thats where 70D come in with a FF sensor and features borrowed from 7D in a 60D body.

So basically,

70D -> FF + some 7D features + 60D body priced above the current 7D - around $1500 or $1600.Or this can also be a new line up. say 6D or 70Dx and 70D could still be an upgrade to the current 60D.

7D -> APS-C or APS-H with upgrades taken from 1Dx and 5D3 -> 61 AF, 10 - 12 fps, dual digic 5, higher ISO ( 2 stops more) and low noise at higher ISO, better IQ and probably 22MP if APS-C or 16-18MP if it is APS-H (would be happy if they resurrect the legendary APS-H, but with cameras moving towards mirrorless, canon is unlikely to have an extra burden to continue APS-H sensor parallel to their current active sensors).Making it the top Crop DSLR, very much suitable for sports and wildlife as it still has a base crop sensor in its body.

And as all the canon rumors say, 70D will come out first and later 7D2. 70D would come out in September in Photokina along with Nikon's D600 - The 2 entry level FF DSLRs. And after some time, canon would release 7D2, later this year or early next year to haunt the speculated Nikon's D7100.

This is just my opinion, donno what will happen. Have to just wait and watch.

There is value in handholding exposures > 1/10 sec, even if some people refuse to believe it. Brian Carnathan (the-digital-picture.com) has a 1 sec handheld exposure with the 15-85mm IS on his review (including a 100% crop), you can't tell me the stabilization didn't have a significant role in creating that image.

exactly right -- that was my point as well. those who reject the value of IS just don't have the need or desire to shoot these situations, it seems.

Also useful for interior shots inside castles, churches, temples,museums etc. where tripod is not allowed.

IS can benefit multiple-exposure alignment for HDR situations as well. my most recent experience was with my feet in the surf where wind, wet sand, and other dynamic conditions precluded the setup necessary for a tripod.

also very usefull when you are standing on a vibrating platform trying to shoot in low light

Make sure the lens is weatherproof if you are going to take pics on the waterbed

LOL i would have got a pic of the 1D and 24-105 covered in iron ore but i was too busycrying like a little girl and trying to clean it all off with disposable glasses lens cleaning alcohol wipesthese do an amazing job by the way. It did cost me $175 to have the iron ore removed from the focus ring though hence why i would prefer a non telescoping zoom

This is why I also think remaking the xxD into the FF entry level, swivel screen + 24 - 105L for your 2000Euro makes the most sense. For this price it cannot be magnesium alloy and fully weather sealed or 100% viewfinder. All attributes I will more likely attribute to the xD line than mere sensor size (from a marketing point of view)
